A quadrilateral is a four sided shape. The regular quadrilateral shape is a square or rectangle: each angle is 90 degrees. An irregular shape is when the angles are different than the angles they should be.
E.g: Square = 90. 90. 90. 90. -360 Degrees.
Triangle= 60. 60. 60. 60. -180 Degrees.
The irregular shapes would have different angles.
